Abstract

Four strains of anamorphic yeasts isolated from the fruiting bodies of mushrooms collected in Taiwan were found to represent two novel yeast species belonging to the genus , which was formally known as the clade. Strains NY13M09 and NY14M14 were related to the type strains of , , and , and strains GG4M07 and GG6M14 were related to NRRL Y-17087 and NRRL Y-27777. However, strains NY13M09 and NY14M14 differed from their closest phylogenetic neighbours by 2.9–3.7 % in the D1/D2 domain sequence of the LSU rRNA gene and by 6.6–13.7 % in the internal transcribed spacer (ITS); GG4M07 and GG6M14 differed from their closest known species by 2.4 % in the D1/D2 domain sequence of the LSU rRNA gene and by 8.7–10.0 % in the ITS. Meanwhile, these strains were also clearly distinguished from their closest relatives based on the results of physiological tests. Based on the characteristics described above, the strains could be regarded as representing two novel species of the genus , for which the names sp. nov. and sp. nov. are proposed. The holotypes are BCRC 23475 and BCRC 23476.
